Reflashing stock FIRMWARE - Galaxy Grand Duos i9082 Q&A, Help & Troubleshootin

Deleted a few system apps' with root uninstaller by accident on the phone, been trying for a few days to fix it, though failed. Thinking about re flashing the official firm ware. And hopefully getting the phone back to it's fully working order again.
It's currently running on 4.1.2, phone rooted, using I think a stock ROM though have CWM.
As said I want to reflash 4.1.2, this webpage (below) is about updating to 4.1.2. Can I still use the links/info on this web page? Its this relevant? http://www.android.gs/update-galaxy-grand-jelly-bean-4-1-2-xxamd6/
Or maybe members could be so kind to add a better link with instructions how to reflash my phone on stock firmware.?
I hear that 4,2.2 has some minor issues? So guessing 4.1.2 is a better? Or how about 4.4.Kitkat?
This might sound stupid, do I uninstall CWM before I reflash firmware? So I don't need to uninstall first 4.1.2,to install new 4.1.2.right? I am obviously a newbie, steep learning curve
Any links/info' help will be much appreciated, thankyou,
Alex

[Q] Update Stock Rooted

I've been searching arround but can't find a solution for my issue; i have a rooted desire, with a stock rom with a modified kernel (for the battery fix); i got an OTA but i can't seem to apply it. I've even toggle dthe signature (and the other thing you can toggle, can't rememebr what its called!) through recovery but even then the installation gets aborted.
How can i apply the OTA? i don't mind loosing root 'cause it's easy enough to do if i want it again.
And i know i can just flash a newer rom but from my experience (winmo), if i start flashing roms, i'll never stop!!!
UPDATE: Ok, now i've messed up; I restored my previously backed up version (old kernel), then rebooted the phone, istalled the update and now it just boots onto htc splash screen then reboots. I can boot into hboot but when i try and go into recovery i get the picture with the phone and a red triangle with an exclamation mark inside!
Help please!!!
****ING NOOBS!!!!
Seriously, read the other threadas about how you CANNOT APPLY AN OTA TO A ROOTED ROM WITHOUT CAUSING ISSUES!!!!
The point is it wasn't a rooted Rom, it was a stock Rom with a stock kernel but a rooted phone.
And seriously man, if you're not going to help just f*** off.

Hey..Stock Kernel+Unrevoked=Rooted Stock Rom..
It wont take in an OTA..
If you need the OTA, you do need to unroot.
Ok then, i obviously messed up.
Now i'm downloading a stock rom and i'm going to flashh the ruu throgh fastboot. Should that work?
Any advice would be really great guys, i just want to get this fixed.
It should..
Ok, i'll try that and report back in case anybody finds this thread helpful in the future!
Update: it worked! I'm out of the woods!!
Note to self (and anybody else who dosn't know): OTA are a big no-no for andt rooted device, no matter what rom or kernel you are running!!

[Q] Weird Firmware Update issue

So, I had kept my S3 on ICS up until earlier this evening. For the past week, my phone would pop up with a 387.38mb downloadable update that it would only do on WiFi.
I assumed this was Jelly Bean, so I just went ahead and downloaded Kies, because my PC can download the update much faster.
I had downloaded the update before, but the fact that I was on custom recovery and rooted caused it to fail every time. I went and unrooted, and reinstalled normal recovery, just so I could update. I did the JB update, then rerooted and reinstalled custom recovery.
I'm still getting the notification and download prompts for the previously mentioned update.
Does anyone know what it is? I feel like an idiot for asking, but I have Google searched and found nothing. in fairness, I am tired and have had long day, so its highly likely I missed something. Please inform me. Thanks in advance.

What is your current baseband version? Possibly your update did not flash correctly. I would backup your phone, make a nandroid, wipe data/factory reset, wipe cache, download and flash stock JB via odin and wipe data again. There are 2 JB versions available in the Android dev thread. One is stock with root injected and the other will require you to root again after flashing if you want.
I'm on Baseband i747UCDLK3, which as far as I know is the latest update.
My solution was to go in to Titanium, find the app that handles updates (in this case its called "AT&T Software update V4_1_1210_2_2"", and freeze it. No more annoying nags about an update, so far.
I'll have to see how well it works. It's only been disabled for about ten minutes, but if I don't get nagged anytime by tomorrow, this thread can be considered closed, since I'll have figured out the solution.
EDIT:
Its been more than 24 hours without the nag. This solved the issue, so this thread can be marked as answered and closed.

[Q] Official stock rom Help?

First of all, yes, I am an idiot, and yes, I have looked through the forums but just have to make sure I am downloading the correct thing.
So, a while ago, I rooted my t-mobile galaxy s3.
Today, I wanted to download a root-compatible app, it didn't work, turns out that my root somehow became disabled ( I might have accidentally wiped the superuser binaries)
So, I try to re-root my phone...several times. I finally think I have it rooted (using the official xda guide on how to root), and everything was fine, until i try to use superuser and it turns out that I am not rooted...for whatever reason. I do a hard reset a couple of times, it still shows that I am running alternate software and cannot update. I try to flash a stock rom to my phone, and that just simply fails on odin.
Now, I have completely formatted the SD and internal storage (probably very stupid), and I am just wondering how I could possibly flash a stock rom onto my phone, and if you could please link one because I believe the one I tried was not for my device.
If not, please provide some suggestions on what I should do. My device works, so it's not really time-sensitive, but I do want to re-root my android after I revert to stock roms, properly this time.
Thank you for your time and help!
Fixed
Fixed the problem, will be posting tutorial in the morning for anyone who might have the same issues!
Waiting for u!!

How to update from stock root 4.1.1 to current?

I'm sure this has been addressed but I can't seem to find a definitive answer. I am bone stock (stock recovery and no custom rom) with just root on AT&T.
There are no missing deleted apps, as I replaced them previously but I still have never been able to do any of the OTA updates. It's starts and then fails.
Is there a way to unroot and the do an OTA update? I am trying to avoid Odin so I dont have to wipe everything and then have to start all over and adjust settings to my liking an also reinstall all of my apps.
I seen there is an option in the Super User app to "completely unroot and uninstall". Will choosing this option allow me to finally do OTA?
I've never installed a custom recovery or a custom rom so I don't know why OTA's always fail. At this point, I dont really care about having root since the only reason I previously wanted it was to remove at&t bloatware but I'd rather have OTA's at this point.
Any advice or direction would be greatly appreciated! Please speak slowly and in layman's terms as I am an old fart that is still a bit of a n00b, lol.
Thanks!!

If you are on stock and have a valid AT&T SIM card in the device with full access to Wi-Fi and the AT&T network, you should be able to get an OTA update. Root could, however, indeed prevent an OTA update so your best bet may be to unroot. You could unroot and uninstall SuperSU from the SuperSU app just as you suggested. This should do it. However, if it doesn't and you would really want to avoid Odin and custom recovery, then you could do a 2-step manual update to 4.3 via stock recovery - first to 4.1.2 and then to 4.3. This will naturally update your phone to (full) stock 4.3 and we can then see if the phone will take the Kit-Kat OTA update from there.
You can see the instructions for the 2-step update via stock recovery in the thread below ...
http://forum.xda-developers.com/showthread.php?t=2387423
1) Download the 2 zip files under update412.zip and update43.zip respectively to your computer
2) Copy the zip files to a good quality (micro) SD card
3) Place the card in your phone and boot to recovery mode by simultaneously holding down the Volume Up, Home and Power buttons
4) Hold the buttons until you see a blue message flash across the screen. Then release the Power button but continue to hold the Volume Up and Home button until you see the Android image appear. Then release the buttons
5) Use the volume up/down key to scroll to <mount from external storage> and the power button to select
6) Navigate to the first zip file (update412.zip) and install. Wait for installation to finish and your phone to reboot.
7) Complete set up. Check your phone settings. Then power off and reboot to recovery again.
8) Repeat the process for the second update file.
Well I tried the unroot feature in SuperSU and then uninstalled it.
I then tried the OTA update again and as usual, it failed about 30-40% in.
Ive never installed a custom recovery or a ROM so I don't get it. All I did was use Mr.Robinsons thread/directions on "how to root without tripping...." just for root only in the sticky.
I give up.:banghead:
Thank you though for responding. I may try the alternative way you suggested when I get time tomorrow and see what happens. Either that or screw it, im stuck with 4.1.1 and now I don't even have root. :banghead:

There have been several reports of failed OTA update so you may not be alone here. The process I advised is sure to take you to 4.3 JB without hassle. There is, of course, a manual update process from 4.3JB to 4.4.2 Kit-Kat (the latest OS). You will, however, require custom recovery for this ...

Well I finally was able to update via OTA. I had to actually use Kies and reinstall firmware and then go through all the updates, starting from scratch and took forever. What an absolute pain in the ass. Plus, after all this work to go from 4.1 to 4.4..........I can't see where it was worth it. I am now going through the tedious task of setting up all the settings and widgets and everything else the way it was or the way I like. So much for Kies actually backing up and "restoring" anything.
I have a couple of questions though....
1. Now that I am on 4.4..........how do I root this version (that works). I was reading the thread saying to use towelroot but it's not confirmed if this is still working after I guess you do the OTA after a certain date and it's now patched. I DO NOT want to install custom roms or anything else. All I want is root so that I can remove the AT&T crapware that is now even worse with this phone on 4.4.
2. I have a battery percentage that is in the LEFT upper corner that I can not figure out what program or app it is associated with and I can not get rid of it. This is not the % indicator that is part of Android and next to the battery icon on the right which is on and is okay, this is one the left.
3. I hate the new PIN lockscreen because the keypad/numbers are so small compared to old version. Any way to fix this?

Glad to know you were finally able to update. To try to answer your questions ....
1. Towelroot indeed comes well recommended for rooting on Kit Kat. You could, however, first try CF Auto Root which is one of the simplest approaches to rooting. If this doesn't work, you could try Option 2 in the thread below ... The thread also contains instructions to CF Auto Root.
http://forum.xda-developers.com/showthread.php?t=2538991
2. I'm not sure what that battery indicator is. I run 4.4.2 also on my S3 but I cant see this. Can you try a reset to see if it would go away?
3. You can try removing this from settings.
Im glad you asked this...
I too noticed Im on 4.1.1 stock but rooted. I wondered if you could go to 4.4.2 as my phone tried to OTA update on its own last week and failed. I did not know if it was worth it to try or not another way. About the only thing I see that would want me to try is Google Wallet now working with S3 on 4.4.2 without having to jump through all kinds of hoops, mine used to work fine, but now GW will not open up all the way. Im not sure its worth doing if I have to re setup all my crap as I will be upgrading my phone whenever I want, just holding out to see if the Nexus 6 will be out end of the year and on AT&T..Im not liking that all the new phones are getting so freakin big, the S3 is just right and I dont want to have to end up with a damn Note sized phone but that is a whole other discussion
If you're still on 4.1.1, BEFORE ANYTHING ELSE, UNLOCK YOUR PHONE IF HASN'T ALREADY
otherwise you'll regret it
then the rest, tbh, you don't need to unroot at all to upgrade, just flash the firmware in ODIN or recovery..
edit: nvm it seems like you've already upgrade yours to KitKat

SGH-T999 Custom ROM with working 4G

Greetings,
I really don't want this to be a repeat post, so I have spent many days now searching for this answer, not just here on XDA if I was honest, I have links to prove it
The aim is to give a little new life to my old phone, and get off the 4.1 build it is on.
With that said, in summary, I have tried a few different custom ROMs; Cyanogenmod 11 - 13, stable to nightly. PAC MAN ROM for Lollipop, some other roms for KitKat I found else where, but in all these I have not been able to get 4G to work. I understand about updating the Modem, and got the latest version from DocHoliday77's post for the Galaxy S3, in point of fact I tried every modem version for 4.3+ on there
But for all this, and it's been time consuming I never managed to actually get 4G to work as stated
I tried playing with settings in Test Mode (*#*#4636#*#*), changed preferred settings, added APN's, rebooting during certain phases of the moon ... but somehow it all avails me diddly.
Finally I have genuinely tried searching for info on if this just isn't going to happen and that's how it is, but somehow I found lots of posts about other models or networks that made it work more than something saying this won't work (putting aside the info on CM 11 that states it's a known issue and won't work on some build I forget).
Which leads me to this post: I wondered if anyone could point me in either the direction of a 4.4+ custom ROM or other ROM, compatible for SGH-T999 (T-Mobile Galaxy S3), that has working 4G. Or how I can get 4G to work on one of the ROMs I have already tried, kind of partial to a nice CM but I am willing to venture.
Also happy to just hear other input about giving new life to the phone so any feedback welcome
Thanks for your time!
NOTES
======
Using TWRP 3.x for flashing
Phone is rooted
IMEI is visible & fine on custom ROM
4G works on stock ROM
not experienced at this but willing to read
Edit: something I had not noticed before, I install Gapps for most of my tests but never use it. I just tried to download from Play Store, it acts as though I have no connection; waiting to download appears, then eventually it says waiting for network. Yet I am able to browse the net fine with the phone floating between 3G & H+. I don't know if that might help, so figured I should add it.
Is the phone running the latest bootloader and modem? Maybe both are needed to properly get 4g on all Roms?

That's a really good question, let me see if I can find out how to get my bootloader info and I'll get back to you.
May I ask what the latest bootlader is for the SGH-T999, or where I could find this so I can compare it? I couldn't seem to find it, though the most resourceful post I did find related was T999 UVDMD5 Firmware / Bootloader by mnasledov, though it is also a little outdated it appears, I haven't read my entire way through it yet sorry, I also know the phone is a little outdated too .
So that wasn't too bad to find out
I don't have the latest bootloader if that should match the baseband I install.
Where after a ROM install I get my baseband to T999UVUEOH1, but the bootloader stays on T999UVDLJA.
I haven't quite found where to get the latest bootloader just yet, though I did really spend the last few minutes discovering about the bootloader; if you or someone could find the time to point me in that direction that would be awesome
Simplest way to make sure you have the latest would be to flash the most recent stock rom from sammobile.com in Odin.
Thank you very much @audit13, I do appreciate the time you took out to help me and I also appreciate the point in the direction of what next.
I'll go dig into that for a while and see what to do to be sure, before I start
Looks like this is the latest one, so I will give this a shot : PDA T999UVUEOH1 & CSC T999TMBEOH1, version 4.3.
So just as a quick question, since I've never upgraded the bootloader in this fashion etc., from what I have read this is a one way street correct? And since I am upgrading to stock, then I guess will I lose root, which I will have to go back down the path of for a reinstall, or could I flash my old back up over this from TWRP and in that fashion have the latest bootloader, but keep everything I have for the moment as I investigate a ROM that will offer 4G.
I guess what I am getting at is even if having the latest bootloader and some other ROM with the latest baseband doesn't give me 4G still, can I go back in terms of the OS version to my 4.1.1 and keep things as is with a newer bootloader?
I will investigate this myself too, I just always preferred some additional input when discovering things where possible.
I do appreciate your time, thanks again!
No, you cannot run stock 4.1.1 on a 4.3 bootloader unless it is a custom 4.1.1 rom based on a stock touch wiz rom.
I do not think it is a problem to run the latest bootloader and modem as the latest custom ROMs often require an updated bootloader and modem.
Once on a 4.3 bootloader, you can't downgrade to something older.
Thanks again @audit13, that matches what I have read, I appreciate the confirmation!
Looks like I will be undergoing a re-root etc. so I'll get my information together, have a little more read, see what I need to back up and then jump down the rabbit hole
I'm grateful for your time and help.
If you decide to run a custom rom, just flash a stock rom, then immediately flash twrp via Odin, then install the rom and gapps. No need to root before hand.
Ahh ok, that would have made the most sense. However I didn't have an opportunity to check back on this thread until now so even though you had awesome speedy reply I missed it.
I did manager to successfully flash the stock ROM from Sam's. It did also update the bootloader so THANK YOU very much for that.
I had to fiddle a little to get Odin to recognize the my Galaxy S3 in the end it was simple: after I installed Kies to get the drivers on, I disabled WI-Fi (I use it for my dev work, and then it didn't try to spend time getting other drivers and it all went great. But that's just a note incase maybe one day someone else reads the thread and wonders how, this might help.
I'm just actually restoring a couple f things on the stock ROM, I figured I would have it ready in the event a custom ROM doesn't suit immediately, as I find one I like, then I have a back up of the stock ROM on 4.3 to revert to. Incidentally I just used TWRP manager from Google play store to install TWRP, hopefully it's the same as the flash, except now I know I rooted when I didn't have to
@audit13 Thanks, I know I keep saying that but I appreciate your time the same way I would hope someone else appreciated mine.
Incidentally once ready I will post an update here about the success of getting 4G on Cyanogenmod 12 or even 13 maybe, or someone of the other custom ROM I try, to share that info.
So just an update, I can confirm even with both an updated bootloader and matching updated baseband there is still no 4G on Lollipop Cyanogenmod 12, haven't quite tried any other yet, that was the one I liked the most but I will carry on and get a list as I have time then update here.
If there are any further suggestions I'm all open to them
Thanks [email protected]
Do you get 4G on a stock ROM? You have an LTE capabale sim? You get 4G on another phone with the same sim card?
Right, this SIM gets 4G on 2 other phones it's been in, on this phone on stock ROM it gets 4G too. Reverting back to stock backup in TWRP, from CM12 looks like it tripped knox I think it is, so now the warranty bit is 1 oops. But I managed to Odin back to 4.3 stock, so now I also need to see if I can try to flash maybe to CM 11, which is 4.4.x, or if maybe I'm stuck here. If I can find out I certainly will update the result of 4G testing.
You've been really patient & helpful thanks!
First let me say I'm a noob. I've rooted and jailbroken devices but I admit it's all from falling instructions. I rooted my s3 a while ago and installed twrp 1.0.8.7 yesterday. I did a full wipe including system and all catches and installed the latest nightly of cm13. Everything is running great. I don't know if this helps but maybe it's your process. Good luck!

That's really helpful thanks @Shack70, since updating to 4.3 I have only tried CM 12, I can certainly give 13 a shot, & you have 4G working then please?
incidentally I have actually recorded every step I performed, in the event I repeat this again or I had to explain it. But my process maybe at fault I agree; I rooted my phone with towelroot. Installed TWERP manager (3.0.2 something, maybe I should try 1.0.8?), rebooted into recovery & first thing was take a full backup on stock. Then I did a factory wipe, & advanced wipe. Then installed the ROM, wiped dalvik/cache. Installed Apps, wipe dalvik/cache, reboot
Hopefully that's not too much? I just wonder if any of those steps raise alarm?
Edit: mind if I throw a few questions on here at you please @Shack70?
what do you wipe from the options please?
after the install, do you run any other wipes please?
how did you get TWRP on your phone? Not sure if that or version matters but I'm willing to try

In twrp I wiped system and all caches before installing the rom and gapps. I installed an older version of twrp using Odin and updated it to 2.0.8.7 using the twrp app in the play store. Yes I have 4g/lte. I've seen it switch from lte to h+ to 3g depending on my location so I'm sure it's working correctly. The camera and Bluetooth also work fine. I hope this helps, I'm still learning and most of what I've done is just by following others instructions here at XDA.

I definitely appreciate the reply thanks!
I gave the latest nightly CM 13 a shot just now, 7/31/16 version essentially. Not finding any issues with the ROM, can't get 4G to show up no matter what though , even with changes and attempts to APN settings etc. None the less maybe to give my phone a rest I'll just stick with this a while and decide if a newer nightly comes out I want to try, or better yet a stable version at some point. Then I can verify how much I really miss my 4G I guess.
All the previous attempts, including this one always results in 3G to H+ network with no issue, it's just that 4G that never shows up for me.
Incidentally without a serious search around I couldn't even find TWRP 2.0.8.7, it's not on the TWRP manager version I have so curious, I ended up just going with 2.8.0.7, thinking maybe it was a typo?
Otherwise I basically run the same type of install you mention, I also clean dalvik, cache, system & data in my case. Just to confirm that.
I have a slightly off topic question here, if I decide to go back to to stock I was wondering, if i went from UVUEOH1 4.3 JB build, to the previous UVUENC2 4.3 JB build; because I've seen this available as a clean route 66 version, is this still considered a downgrade and a bad idea? I'd be flashing with Odin from @DocHoliday77 post here.
@Shack70, thanks for the input, thanks for the guide on your steps, glad I've confirmed I'm doing the same even if I can't get my 4G, hopefully someone on a Galaxy S3 T-Mobile, went through this found a solution, and maybe will let me know what they did too, not sure if you are on T-Mobile or not. 
 @audit13, also thanks, you've been replying plenty too and I appreciate that also!
One small thing I just came across looking over the logs of the install.
When flashing CM 13 with TWRP, I noticed it said the Target: samsung/d2tmo/d2tmo:4.3/JSS15J/T999UVUEMJC:user/release-keys.
Is it normal and OK for it the be referencing a different baseband/bootloader than what I actually have on my phone?
UVUEMJC vs the UVUEOH1? Where the one as named by TWRP flash is 2 versions older than what I have installed? Not necessarily stating this is an issue, just asking please if this is normal, and I also understand it could be something I have overlooked in my reading, it's been a lot of reading
I would not worry about the referenced baseband as flashing CM13 does not change the bootloader or baseband during the flash process.

That makes sense thanks @audit13, just a few of the questions I had building up.
So that my previous question doesn't get lost, and although I know it's a dying phone for users hopefully this might get some visual
